Filed: 1928-05-08
Abstract: 316,688. Siemens Bros. &. Co., Ltd., Grinsted, W. H., and Byard, S. A. May 8, 1928. Automatic exchange systems; simultaneous telegraphy.-Signals are transmitted over a line used for telegraphy by means of alternating current of a frequency within the voice range and rejector circuits are provided for shunting this frequency from the telephone instruments. The alternating current may be used for the distant control and supervision of power apparatus, for telegraphy, or, as shown in the Figure, for controlling selectors in an automatic telephone system. A calling line in one exchange is extended over automatic apparatus SAT to a junction L leading to a sound exchange. Alternating current from a generator TG is sent over the junction and after passing through a tuned amplifier AV and rectifiers RV effects the operation of relay CR. Interruptions in the alternating current produced by dialled impulses received over the path CP are repeated by relay CR to effect the operation of the automatic apparatus RAT in the second exchange. The alternating current remains on the line during conversation so that supervizory signals are given in the same manner as in a direct-current central-battery system. Rejector circuits SR, RR, are arranged as shown to prevent passage of the alternating current to the telegraphic instruments. The input circuit of the amplifier AV may be coupled to coils in the rejector RR.

Title: Improvements in or relating to the Extraction of Ammonia from Gases.
Inventor: PEASE EDWARD LLOYD
IPC: C10K1/10
Filed: 1917-06-22
Abstract: 121,754. Pease, E. L. June 22, 1917. Ammonia is extracted from hot gases, for example gases passing from furnaces or gas-producers, by a solution of a salt, such as calcium chloride or zinc chloride, possessing the property of forming a double compound with ammonia, which is delivered as a shower or spray by one or more distributing-devices provided with spraying-nozzles into a vessel through which the gases are caused to rise. The apparatus may comprise a vessel a having gas inlet e and outlet h, and provided at the top with a liquid-distributing box b fitted with spraying-nozzles d. The vessel a is without internal projections, and is formed with a sloping bottom so that solid matter, for example calcium carbonate formed when the gas treated contains carbon dioxide, is washed out of the vessel. The heated liquid containing the absorbed ammonia leaves the vessel by a pipe c' and enters a box m when the dust and solid matter taken up from the gases, and which float on the solution, are separated by a scraper or filter, for example by a. vertical plate i, a lateral opening m' being provided in the side of the box for the removal of the separated matter. The liquid then passes through a settling tank u to a tank v where it is treated with milk of lime to liberate the ammonia, and the residual solution is returned by a pump z to the vessel a. The ammonia may be absorbed in water in a vessel y, or a plant for producing an acid or an acid anhydride may be provided, the ammonia and acid or acid anhydride being led into a vessel to form a salt; for example, ammonium nitrate may be formed from the ammonia, water vapour, and nitric anhydride made by the known electric treatment of air. When the hot gases contain tar in addition to carbon dioxide, a portion of the tar will be washed out of the gas and will mingle with the calcium carbonate; the mixture is removed in the separating box m and is burnt for the recovery of the lime. The remainder of the tar passes off with the treated gas and may be separated by known means. The hot solution, before treatment to liberate the ammonia, may be utilized for producing steam or for heating water or other liquids as described in Specification 121,752, [Class 64 (i), Heating liquide &c.]. In a modification, the hot gases are 'washed or scrubbed by a water spray in a separate vessel before entering the vessel a; the washing may be carried out to such a degree that the whole of the tar is removed from the gas.
